Made from special alloy material and featuring a high-performance ceramic coating, this sleeve delivers exceptional wear resistance, precise ink transfer, and long service life—making it an indispensable tool for businesses relying on Bobst equipment. Whether used in flexographic printing, packaging production, or large-format printing, the Bobst Sleeve ensures consistent performance, reduced maintenance, and cost-saving benefits.

Key Benefits

Tailored for Bobst Printing Machines

Designed specifically for Bobst printing machines, the Bobst Sleeve offers perfect compatibility and seamless integration with your existing equipment. Its special alloy material and precision dimensions are engineered to match Bobst’s operational requirements, eliminating fitment issues and ensuring optimal performance from day one. Unlike generic sleeves, this product is optimized for Bobst’s high-speed printing processes, delivering reliable results that align with the brand’s reputation for quality.

Durable & Cost-Saving Operation

The Bobst Sleeve features a nickel-chromium alloy underlayer and a special pure chromium oxide (Cr₂O₃) surface layer, crafted from imported ceramic powder with smaller particles. This combination provides exceptional wear-resistant, corrosion-resistant, and high-temperature resistant properties, extending the sleeve’s service life and reducing replacement costs. Its robust construction withstands the rigors of continuous printing, minimizing downtime and maximizing productivity—delivering tangible cost savings for your business.

Optimal Ink Transfer & Hassle-Free Maintenance

Equipped with ALE fiber laser engraving, the Bobst Sleeve boasts a precision mesh structure with large ink transfer capacity, smooth mesh walls, and a flat mesh bottom. This design ensures rapid ink dilution, uniform ink distribution, and crisp printing results—even at high speeds. Additionally, the smooth mesh surface simplifies cleaning, reducing maintenance time and labor costs. Whether handling complex patterns or high-volume runs, this sleeve maintains its performance and remains easy to care for.

High-Precision Performance

Precision is non-negotiable in printing, and the Bobst Sleeve delivers unmatched accuracy. With a runout of 0.005～0.01 mm, cylindricity of 0.01 mm, and a dynamic balance quality grade of 8g, it operates with minimal vibration, ensuring consistent print quality and edge definition. The surface finish (Rz: 0.01) enhances ink adhesion and transfer, making it ideal for applications requiring sharp details and vibrant colors—from packaging labels to large-format graphics.

Technical Specifications

Advanced Manufacturing Processes

ALE Fiber Laser Engraving Technology

The Bobst Sleeve utilizes advanced ALE fiber laser engraving to create its high-precision mesh structure. This technology ensures exact control over mesh hole size, shape, and arrangement, delivering optimal ink transfer and printing consistency. Unlike traditional engraving methods, fiber laser technology produces smooth mesh walls and flat mesh bottoms, reducing ink waste and improving coating uniformity. The process also supports custom mesh designs, allowing businesses to tailor the sleeve to specific printing needs—from fine text to complex graphics.

Strict Ceramic Layer Plasma Spraying Process

To achieve the sleeve’s exceptional durability and performance, we implement a rigorous plasma spraying process for the ceramic coating. This process ensures the Cr₂O₃ surface layer has consistent porosity (1～2%), thickness, and uniformity—critical for ink retention and transfer. The nickel-chromium alloy underlayer enhances bonding between the base sleeve and ceramic coating, achieving a bonding strength of 40—60 Mpa. Every Bobst Sleeve undergoes strict quality control during spraying to meet the highest industrial standards and Bobst’s performance requirements.
